Description
technical field [0001] The invention relates to the technical field of converting light energy and thermal energy into electric energy, in particular to a photothermal-electric conversion device for increasing temperature difference. Background technique [0002] With the depletion of fossil fuel reserves, the use of renewable energy such as solar energy has become an important direction of attention. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Photoelectric conversion is currently the main way to effectively utilize solar energy. For example, solar energy can be converted into electrical energy through photovoltaic modules. However, due to the limited photoelectric conversion efficiency of solar cells during operation, which is generally 20-30%, the remaining solar energy is lost in the environment in the form of waste heat. [0003] Thermoelectric materials can directly convert thermal energy into electrical energy and sho...
